Adding USGS WMS Base Layers to QGIS

A screen capture of the Europa WMS.

The USGS provided Europa Global Mosaic, loaded as a WMS.

This is an in progress draft example. Please feel free to test, but use with caution!

In this tutorial, you will learn how to:

  • Add a connection to the USGS Europa WMS server
  • add the Europa Global Mosaic WMS base layer to a QGIS project

This tutorial demonstrates how to connect the the USGS Astrogeology hosted Web Mapping Standard (WMS) server and stream a base layer into QGIS.


This tutorial requires that you have the following tools installed on your computer:

Software Library or Application Version Used
QGIS 3.30.1


The table below lists URLs for WMS layers for bodies that have analysis ready data available. For a complete listing see here
